Hello,
If you want to save the graphical content, you can use File system helpers and GraphicsView.CaptureAsync()
method
Firstly, if you have a GraphicsView like following code.
<GraphicsView
x:Name="myGraphicsView"
Drawable="{StaticResource drawable}"
HeightRequest="300"
WidthRequest="400" />
Then, you can save it from backgroud code. 1. get the IScreenshotResult by myGraphicsView.CaptureAsync()
, 2. Create an output file, copy the graphics to this output file by await screenshotResult.CopyToAsync(outputStream);
.
IScreenshotResult screenshotResult= await myGraphicsView.CaptureAsync();
if (screenshotResult!=null)
{
// Create an output filename
targetFile = Path.Combine(FileSystem.Current.AppDataDirectory, "test2.png");
// Copy the file to the AppDataDirectory
using FileStream outputStream = File.Create(targetFile);
if(File.Exists(targetFile))
{
await screenshotResult.CopyToAsync(outputStream);
}
}
